Definitions
- Oligonucleotides allowing the identification of precursors of amidated polypeptide hormones
- the present invention relates to new oligonucleotides and their application as probes for the identification of mRNAs coding for precursors of amidated polypeptide hormones and, thus, the identification of new amidated polypeptide hormones.
- the invention therefore relates to oligonucleotides whose nucleotide sequence is described below and a method of identifying precursors of amidated hormones.
- Amidated polypeptide hormones are synthesized as a precursor that undergoes maturation. This maturation consists of an amidation reaction.
- the C-terminal amidation reaction is a characteristic reaction of amidated polypeptide hormones. This reaction, which takes place on the precursor of one or more hormones, allows the maturation of the hormone and also ensures its biostability in the physiological medium: the amide group formed is less vulnerable than the free acid function. The hormone is then more resistant to carboxypeptidases, it remains active longer in the cell and keeps an optimal affinity with its receptor site.
- the PAM enzyme (Peptidyl-glycine- ⁇ -Amidating Monooxygenase) comprises two distinct enzymatic activities: first, it converts the extended glycine intermediate into an ⁇ -hydroxyglycine derivative, the subunit of the PAM enzyme which intervenes is PHM (Peptidyl-glycine- ⁇ -Hydrolylating Monooxygenase).
- the derivative obtained serves as a substrate for the second subunit of PAM (noted PAL: Peptydil- ⁇ -hydroxy glycine ⁇ -Amidating Lyase) which fixes the amino function of glycine on the amino acid immediately adjacent to the N-terminal side and releases glyoxylate.
- This reaction requires the presence of a recognition site on the precursor of one or more hormones, a site which always includes the sequence: glycine and two basic amino acids (arginine or lysine).
- Amidated polypeptide hormones which are intended to be secreted out of the endoplasmic reticulum are known to contain a consensus signal sequence of about fifteen to thirty amino acids, this sequence is present at the N-terminal end of the polypeptide chain. It is cut later by an enzyme signal peptidase, so that it is no longer found in the protein once secreted.
- Proteins can be isolated and purified by various techniques: precipitation at the isoelectric point, selective extraction by certain solvents, then purification by crystallization, countercurrent distribution, adsorption, partition or ion exchange chromatography. , electrophoresis ...
- precipitation at the isoelectric point selective extraction by certain solvents
- purification by crystallization countercurrent distribution
- adsorption partition or ion exchange chromatography.
- electrophoresis ...
- these techniques imply knowledge of the properties of the protein to be isolated.
- it when you have a pure sample of a new protein that is interesting from a therapeutic point of view, there are still many steps before you have a genetically modified microorganism capable of synthesizing it.
- the method proposed by the present invention offers the advantage, by the use of a particularity of the peptide sequence of the precursor of all amidated hormones known to date, of allowing the simultaneous detection of several new hormones of this category.
- This research is carried out by direct identification of the nucleotide sequence coding for said precursors in cDNA libraries prepared from tissues in which the precursors of these hormones are capable of being synthesized.
- this invention saves considerable time and money in a sector where research and development expenses represent a very large proportion of turnover.
- the present invention will also allow the pharmacological study of active substances having a fundamental physiological role in the organism of mammals: hormones and more particularly amide polypeptide neurohormones. Having first of all the cDNAs corresponding to the active substances, it will then be possible to introduce, by genetic engineering, the cloned vector to conduct the synthesis of hormones having a therapeutic application by microorganisms.

Itakura, JJ Rossi and RB Wallace, Annu. Rev. Biochem., 53, 323 (1984).
